The Good Karma List Machine is a script that I can set up on my website. There is an admin control panel which I can use to control the script. It is script that controls opt-ins and tracks referrals. Newly opted in customers are given a special link and if others opt in under that link they get points. After a certain number of people have signed up under a link that user gets a reward.
Similar to: http://www.easycashmethod.com/ and other viral marketing scripts.
I have attached the script. The script works well the only problem is once I the admin password is changed it won't let me log back into the admin panel.
